Reference return buggy notice?

["Ondra Zizka" <zizka@xxxxxxxxx>]

Hello,

please look at the code bellow and tell if it does not conform to rules of 
returning a reference from a function.
In the first method, I return reference to $sRet variable, and PHP is quiet.
But in the second, PHP says:

Notice: Only variable references should be returned by reference in 
C:\web\php_bug_reference_return.php on line 8   // return $ref =& 
$this->ReturnReference();
(Note that the notice does not concern the first method as the notice 
appears even if I remove references from the first method.)

But I am still just returning a reference to a variable, so I guess it's 
actually correct, isn't it?

Thanks for oppinions.

<?php
class A {
 function &ReturnReference(){
  $sFoo = "Hi.";
  return $sRet =& $sFoo;
 }
 function &RequireReference(){
  return $ref =& $this->ReturnReference();
 }
}

$oA = new A();
$ref = $oA->RequireReference();
?>
